Drought Vulnerability of Illinois' Community Surface Water Systems, Illinois State Water Survey

Illinois Drought


System Information

System Description

Water is pumped from an intake on Highland Silver Lake via a wet well to a 2.2 mgd treatment plant. This system sometimes is listed as a recipient of purchased water from East St. Louis (Illinois-American) only because the village of St. Jacob receives part of its water from Bond-Madison WD, which, in turn, receives its water from East St. Louis.

Developments since 1989:

Highland is evaluating possible sedimentation reduction projects. This includes a coffer dam on the north side of the lake and fencing off a grazing ground just north of Interstate 70, which bisects the lake. Algae caused minor taste and odor problems during the 2005 drought.
